Thief Production Issues?

A post
on Polygon calls the state of the Eidos Montreal's upcoming Thief reboot
into question, saying they've learned from "anonymous sources familiar with the
studio" that the project is suffering from inflated production costs and staff
departures attributed to "corporate politics, creative confusion and a lack of
publisher oversight." They say that the team has had to spend a lot of effort on
creating press demos, and that "many programming tricks" are required to run
their demo, going so far as to say "the vertical slice doesn't load inside
Thief's current heavily modified version of Unreal Engine 3," which is hard to
understand (it makes it sound like the demo doesn't actually run). They say that
Square Enix is growing concerned with this situation, noting that a portion of
the recent GDC demo video was to be released to the public, but a source tells
them this plan was scrapped because Square Enix was unhappy with the quality of
the footage. They conclude noting the game is still slated to be shown off at E3
this June.
